Updated: 11 August 2026.
ODIS GEKO and related online procedures can stop with an FAZ or ERP message when the vehicle, component, key, account permission or requested operation does not meet the required conditions. The code should be recorded exactly as displayed. Do not repeatedly retry an online operation before checking the vehicle and component information.
The descriptions below are a workshop-oriented interpretation of commonly encountered messages. The complete ODIS test plan and current OEM repair information remain authoritative because the result can vary by vehicle, control unit and operation.
Common ODIS GEKO error codes
| Code | What the message generally indicates | First checks |
|---|---|---|
| FAZ2781E | The component is reported as locked. | Confirm the component identity, source, vehicle assignment and the requested guided procedure. |
| FAZ4990E | The component is reported as disabled. | Check the part number, diagnostic history and whether the component is eligible for the requested operation. |
| FAZ9484E / FAZ9488E | The component is reported as damaged or not adaptable online. | Complete hardware and communication diagnosis before attempting another online adaptation. |
| FAZ2946E | A used instrument cluster may not be eligible for the requested procedure. | Verify whether the repair procedure requires a new or specifically prepared replacement component. |
| FAZ1224E | A problem is reported with the instrument-cluster data. | Check cluster identification, stored faults, power supply and the correct replacement procedure. |
| FAZ1243E | A problem is reported with gateway data. | Confirm gateway communication, part information, vehicle configuration and existing faults. |
| FAZ1531E | The key is reported as already assigned to another vehicle. | Confirm the key source and eligibility. Do not continue until the correct authorized key is available. |
| FAZ1532E | The supplied key is reported as ineligible or aftermarket. | Verify that the key and part number meet the current OEM procedure for the vehicle. |
| FAZ1552E | The key or associated order is reported as no longer valid. | Check the current order status and key eligibility instead of relying on an old validity assumption. |
| FAZ9113S | The operation could not be completed and requires further investigation. | Save the full message, diagnostic log and operation details before contacting support. |
| ERP4711E / FAZ4160E | The account or user does not have permission for the requested function. | Confirm that the correct service and authorized access are being used for that vehicle and operation. |
Do not replace a component based only on a code
An online message can identify an eligibility or data problem, but it does not replace normal workshop diagnosis. Before replacing a control unit, verify power, ground, network communication, part number, vehicle assignment and the relevant guided test plan. Record the original data before making changes.
Information to collect before contacting support
- The complete FAZ or ERP code—not a shortened version
- A screenshot showing the full ODIS message
- Vehicle make, model, model year and VIN when requested
- The target module, address and part number
- The exact guided function being performed
- Whether the component is new, used or previously installed
- A current vehicle scan and details of earlier repair attempts
Basic troubleshooting sequence
- Stop the operation safely and save the diagnostic log.
- Confirm stable vehicle voltage and module communication.
- Check that the correct vehicle and component information is displayed.
- Verify that the requested service matches the actual guided function.
- Resolve hardware or communication faults before retrying.
- Contact support with the complete evidence if the message remains.
Permission errors versus vehicle errors
ERP4711E and FAZ4160E relate to authorization for the requested operation. Other FAZ messages may relate to component status, data or eligibility. Changing an account cannot repair a damaged module, and replacing hardware cannot correct an access permission problem. Identifying the error category first prevents unnecessary parts replacement.
Related services and preparation
Review the ODIS GEKO requirements checklist before an online job. For a GEKO-related request, see the ODIS GEKO Online service. If the message appears during an SVM operation, use the dedicated ODIS SVM service and provide the complete job details.
Authorized use
Key, immobilizer and protected diagnostic operations must only be performed for a legitimate vehicle owner or authorized workshop repair. Proof of ownership or customer authorization may be required. Error-code information must not be used to bypass anti-theft protection or conceal vehicle identity.
